IMPROVEMENTIN COMBINED STEERING AND PROPELLING APPARATUS.

Specification forming part of Letters Patent No. 172.367, dated J annary18, 1876 application filed November 13, 1875.

To all whom it may concern:

Be it known that I, JOHN H. ALLYN, of Whitesboro, in the county ofOneida and State of New York, have invented certain new andusefullmprovements in Steering and Propelling Devices for boats oncanals and other navigable waters; and l do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing, which forms part of thisspecification.

This invention, which is more particularly designed for boats on canals,relates in part to combined propellers and rudders made capable of beingelevated out of the way, or of being lowered to suit various depths ofwater. The invention consists in a combination of a submerged tiller, arudder pivoted at its inner end to the latter, to admit of the rudderrising and falling on the tiller as a base, as well as of being turnedby the latter. The invention also consists in a combination of apropeller with a rudder and a tiller, to which the rudder carrying thepropeller is hinged. Furthermore, the invention consists in a hinged orrising and falling rudder constructed of a sled-runner or shoe shape onits lower edge, to facilitate the passage of the rudder overirregularities on the bottom surface of the water-course.

Figure 1 represents a plan of the stern end of a canal-boat with myinvention applied, and Fig. 2 a side view of the same.

A is the hull of the boat, or, rather, stern portion thereof. B B is thepropeller-shaft, made in two sections, united by a universal joint orcoupling,0, outside the stern. The shaft'section B is within the boatand driven by the engine, while the other shaft-section, B, whichcarries the screw or propeller 1), projects in rear of the boat. E isthe rudder, which, when down, has its length 1n direction of that of theboat and of the shaft section B under which it is arranged, and withwhich it is connected by a bearing, b, for said shaft-section, in rearof the universal coupling 0, or between the latter and the propeller D.The inner end of the rudder is supported by and hinged to the tiller E,which here is arranged below the propellershaft, and serves not only asa tiller, but a rudder-support also. Thus, the inner end of the rudderis connected,

by a yoke, c, and pivots d, with stanchions e on opposite sides of theworking center or axis f of the tiller. This combination of the rudderand tiller not only provides for the working of the rudder to efl'ectthe steeringas, for instance, by tiller-ropes or chains 9 g and WindlassG--but also for the raising and lowering of the whole rudder from itshinged attachment with the tiller, as by a rope or chain, h, andWindlass H. By the connection of the propeller with the rudder it alsois raised and lowered in common with the latter, and both the rudder andpropeller may be thrown or raised up against the stern of the boat andout of the way by the same means, when it is not necessary that theyshould be submerged. Said rudder and propeller may also be adjusted, asby a ratchet, i, to any desired amount of submersion, or to suitdifferent depths of draft. Said rudder, with attached propeller, isfree, however, to ride over obstacles in the bottom of the canal, nomatter in which direction the boat is going; and to this end the rudderis of sled-runner or shoe construction on its lower edge, which may eventravel on the canal-bottom to aid in support of the rudder andpropeller. In this way the rudder and propeller are protected frominjury, and the propeller, which works within or at the back end of therudder, is further protected from fouling by means of a guard, I,carried by the rudder.

I claim- 1. The combination, with the submerged tiller F, of the rudderE, pivoted or hinged at its inner end to the latter, to admit ot'therudder rising and falling on the tiller as a base, as well as of beingturned by the latter, essentially as described.

2. The combination of the propellerD with the rudder E and the tiller F,to which the rudder carrying the propeller is hinged, substantially asspecified.

3. The hinged or rising and falling rudder E, constructed of asled-runner or shoe shape on its lower edge, essentially as and for thepurpose herein set forth.
